FLUTEIJ SPINDLE.

Application filed December 22, 1923. Serial No. 882,304.

in the county of Lancaster, England, have invented Improvements in Fluted Spindles, of which the following is a specification.

' These improvements relate to spindles for the dyeing or analogous treatment of yarn packages in bulk, as set forth for instance in the specification accompanying pending application for United States Patent filed under No. 640,539 on the 21st May, 1923,

wherein a certain process is described for;

the dyeing of yarn cheeses, in compressed form, on fluted spindles secured within a base plate. It is essential in the employment of spindles for such a purpose, to ensure that the said spindles shall be straight and that the fins thereof shall be flat throughout.

As yarn contracts on treatment with liquids as for instance in dyeing, the necessity for fluted spindles in which the flutes are absolutely straight is at once apparent, as a bent edge involves waste by distortion of the yarn package in removing it from the spindle, if not in the placing of the dry yarn package thereon previous to treatment.

This invention consists in constructing the fluted spindle as hereinafter fullydescribed and claimed.

In the accompanying drawings to which we will now refer two forms of spindle are shown, and it will be understood that any convenient number of flutes may be provided in a spindle by the same means. Figure 1 shows in cross section a spindle having six flutes, Figure 2 is 'a fragmentary elevation of such spindle; and F lgure 3 is a cross sectional view of a spindle having ten flutes.

In Figures 1 and 2, 4 and 5 arechannel section members which are formed by means of drawings through an appropriately shaped die in the manner well known in the drawing of metals. The member 4 is as will be seen equal to member 5, and they have each diverging walls 6, 7, and 8, 9, respectively. 10 is a flat plate of appropriate width. The walls, 6, 7, and 8, 9, and the width of the plate 10, are such that when the members are riveted to ether by rivets 11 at intervals along the p ate 10 and the walls 6, 7, 8', and 9, are angularly equidistant, a cheese of yarnshow n dia ammatically in Figure 1 at 12, can-be'shpped upon the spindle, its inner wall touching the ed es mentioned.

In igure 3 is shown by wa of example cross section of a fluted spind e having ten flutes, formed of member 13 and 14, 15 and 16, and the central flat plate 10. 13 and 14 as will be seen are of the same shape in cross section and are prepared by drawing the metal through the same die; 15 and. 16 are similarly formed in another die. Thus by the use of a single die the members 13 and 14 are formed'with diverging walls 17 ,1

18, 19, and 20, and the same refers to members 15 and 16, which are formed with the walls 21, 22, 23, and 24. The manufacture of a spindle according to these improvements, with eight'flutes radially equidistant, will be understood from this last example, the walls 17, 18, 19, and 20 of members 13 and 14, and the walls 21, 22, 23, and 24, of

members 15 and 16being at the'necessary angle to make them angularly equidistant when the four members are riveted to gether, the central plate 10 being in this case omitted.

The parts may be of non-corrodible or other metal and the edges of the drawn members and of the flat plate may be in each case rounded as shown in the drawings.

We find that spindles formed as described are particularly useful in the dyeing of cheeses of yarns which have tobeslidden on and removed from thespindle as stated,

)but we do not confine Ourselves to that particular use of a spindle so formed.

We claim 1. A fluted spindle for supporting yarn, comprising a flat center late, and side bars secured to the center p ate, each side bar comprising a middle portion which bears on the center plate and straight and flat side portions which project at an angle to its middle portion, t e outer edges of the center plate and of the side bars which come in contact with and support the yarn being arranged at equidistant-points on the circumference of a. circle havin its center substantially at the middle of t e width and thickness of the center plate.

2. A fluted spindle, comprising a flat 2 1,54a,eeo

plate, and a plurality of bars secured one its center substantially at the middle of the over another and arranged on opposite sides width and thickness of the fiat plate. 4 10 of the fiat plate and secured to it, said bars In,te stimony whereof we have hereunto being all channel-shaped in cross-section and set our hands.

- the inner bars having theiredges spaced wider apart than the outer bars, the edges of JOHN BRANDWOOD.

all the bars and of the plate being arranged THOMAS BRANDWOOD. at equidistant points around a circle having JOSEPH BRANDWOO D.
